Getting HTTP response code 400

Chr(34) is a quote character. I'm not sure what you mean when you say you changed a string into a string using Chr(34). To pass any string as a URL parameter you should encode it using roUrlTransfer.Escape() or something similar.

Thanks markn for reply. Actually i have parameter like:

param = {"abcd":{"isDevice":false,"soapRequest":{"cMedium":"WEB"}},"searchCustomerProfileRestRequest":{"soapRequest":{"customerSearch":{"address":{"streetAddress1":"NT=","unitNumber":"NzY0Mg==","zipCode":"MyMTk="},"sessionId":""}}},"ProfileRestRequest":{"soapRequest":{"sessionId":"","searchSelectionChoice":{}}},"queryBadDebtRestRequest":{"soapRequest":{"sessionId":"","firstName":null,"lastName":null,"emailAddress":null,"socialSecurityNumber":null,"telephoneNumber":null,"creditCheckConsent":false},"dateOfBirth":null}} 

i have to send it as a http post request.

If i paas parameter here:

url.AsyncPostFromString(param)

it gives me syntax error , b/c parameter should be in string form. So i am not understanding how to pass param here.

Oh when you said it was JSON data I thought you meant you had already converted it to a JSON string. This was already discussed in your other thread: viewtopic.php?f=34&t=89668. You should use FormatJSON to convert the AA to a string, and then roUrlTransfer.Escape to escape the metacharacters so that it can be passed in a URL. Note however that the server must be set up to expect the data in JSON format. If it's expecting some other format then you need to convert to that format rather than JSON.

Markn,
If i use

FormatJson(param)

here. It gives me syntax error.

Can you post a complete function that exhibits the problem and the exact error message? I don't see any way that the line you posted can produce a syntax error message.

You can either start with a valid JSON value in a string, that you got from a server or built yourself, or you can start with an object representation, i.e. an associative array.

If you are starting with a JSON string value, but you want to change some values or otherwise manipulate it, you can first convert it to an object representation using ParseJSON.

Then, when the object representation is the way you want, you can convert it to a JSON string value using FormatJSON.

You should sent that string value as the parameter to your AsyncPostFromString call.

(I doubt you want to do any escaping at that point, as the POST is sending data, not a URL).

Example:

s = "{'a':'z','b':2}"
s = s.Replace("'", chr(34))
print s
REM {"a":"z","b":2}

o = ParseJSON(s)
o.b = 3
s = FormatJSON(o)
print s
REM {"a":"z","b":3}

Actually i want to know :
is Roku support to post json data? I need same as:-

viewtopic.php?f=34&t=64647&sid=988df4e8559d24ee1b525b7f17590cc82

please Roku confirm that: is Roku support to post json data?

Sure, you can post JSON data. 🙂 From your initial post here, you already know how to POST using AsyncPostFromString.

If you are setting the Content-Type header appropriately, as you indicated, and have verified that the string you are posting is valid JSON, then perhaps you need to diagnose from the service that you are sending to that the data contents conform to the protocol it expects.

thanks Roku, But problem occuring here:

param={"abcd":{"isDevice":false,"soapRequest":{"contractAcceptanceMedium":"WEB"}},"searchCustomerProfileRestRequest":{"soapRequest":{"customerSearch":{"address":{"streetAddress1":"UgRnJhbmtsaW4gU3Q=","unitNumber":"NzY0Mg==","zipCode":"MjMyMTk="},"sessionId":""}}},"selectCustomerProfileRestRequest":{"soapRequest":{"sessionId":"","searchSelectionChoice":{}}},"queryBadDebtRestRequest":{"soapRequest":{"sessionId":"","firstName":null,"lastName":null,"emailAddress":null,"socialSecurityNumber":null,"telephoneNumber":null,"creditCheckConsent":false},"dateOfBirth":null}}

when i use :

url.AsyncPostFromString(param)

---->it gives me syntax error in param why? what is wrong in param here.?

if i am not wrong param should be in completely string form here.
According to you

you can post JSON data using AsyncPostFromString(string)

but it does't allow me post my json data here as a parameter. giving syntax error in param.

and Please share an example where we are sending JSON as part of a post request.

Thanks
